320-328 Walnut St, San Francisco, CA 94118

The three-unit multi-family residential building at 320-328 Walnut Street in Presidio Heights, owned by Koon Fmly Tr, has undergone significant renovations and improvements over the past several years. Built in 1904, the three-story apartment building has seen substantial updates between 2018-2022, including a major facade renovation in 2018 ($40,000) that involved removing non-historic elements, installing new wood double-hung windows, and replacing various structural elements. The building received a new roof in 2019 ($23,700), and more recent work has included electrical upgrades (new subpanel in 2022 and rewiring two units in 2021) and plumbing improvements, such as shower pan installations (2019) and a sewer/housetrap replacement (2021).

Earlier violations from 2007 related to fire safety and rear stair maintenance were all abated by January 2008, and while there were some complaints about construction debris and window installations in 2018-2019, these issues were resolved. The property has maintained active upkeep through various permits and improvements, with recent work suggesting ongoing maintenance of building systems and compliance with current standards. The most recent significant building work includes electrical and plumbing upgrades, while the building's exterior has received attention through various renovations and repairs.

The property has experienced several parking-related issues based on recent 311 calls (2024), but these are external to the building itself. A notable withdrawn planning proposal was for alterations and a rear addition to modify unit configurations and improve amenities, though this was not pursued. The only recorded fire incident was a minor water or steam leak with no injuries reported.
